The Ether Light XT Insulated from Sea to Summit is an ideal sleeping pad for your mountain bivouacs if you are undertaking a trek such as the GR20 or the Tour du Queyras. It will delight hikers concerned about comfort and lightness. With its 10 cm thickness, the Ether Light XT Insulated is very comfortable, ensuring a restful sleep whether you sleep on your back or side, without fear that your hips and shoulders will touch the ground. Thanks to the Air Sprung Cell™ point-welded model, the air cells are interwoven with TPU, resulting in ultra-comfortable voluminous air pockets compared to a traditional mattress. Available in three sizes (small, regular, and large), choose the dimensions that suit your body shape. The Ether Light XT Insulated comes with a storage bag that also serves as a pump sack to inflate your sleeping pad. To inflate it, trap the air in the pump sack attached to the valve and empty the pump sack into the pad. By using the pump sack, you limit the risk of mold inside your pad often caused by the moist air blown by mouth. To deflate it, simply open the valve!
